From a practitioner regarding Polygonum80 (Black Pearl Juice):

“ . . . Polygonum 80 happens to be one of the formulas which I, myself, use regularly. This formula is used by professional athletes under my care as well as Kidney-deficient people, frequently elders, and the overworked. For myself, I started with a teaspoon daily and noticed an increase in energy and a feeling of overall vitality. It is not a wiry, caffeine-like buzz. I sometimes cut back to a half teaspoon when I feel it too much because as you know, abundant energy lacking a mission can stagnate.   

Polygonum (he shou wu) is a fantastic, fantastic, herb; unfortunately it is rarely prescribed in large enough doses or taken over a long enough period of time to be effective. Tonic herbs, are super potent foods and should be an integral part of a daily diet (if suited for the individual) - especially for the elderly.

I compete in intense sporting activities and compensate for my proficiency xu, with a high infusion of energy and determination. By taking doses of herbs consistently (Polygonum 80, Ortho 212, and Cardio are my favorites), I maintain a higher level of energy, drive, and I experience a reduced recovery time. How do I know this? –Because when I forget to take them, my energy drops down, I become less motivated, and recovery time is slower. Choosing between that and the way I feel now . . . I’ll take the herbs. I’ve been taking them for years and I see them as simply a part of my diet - and at half the cost of a cup of coffee, I save money too.

Fresh teas and fresh liquid concentrates are high octane fuel, and when I use "regular" instead, I notice a difference. Whether one needs to alter energy levels, redirect energy, or quell a pathogenic factor, etc., fresh teas and fresh liquid concentrates work miraculously –like the way practitioners prescribing manufactured pill and powder concentrates can only dream of.

From my experience, it is clear that a manufactured pill or powder concentrate will rarely do anything significant, if anything at all. If I had to work all day in a rice field far from home, I might have some herbal pills with me; otherwise, forget it.”
